[PATCH v2] crypto: ccp - Log an error message when ccp-crypto fails to load

[Hook, Gary]

From: Gary R Hook <gary.h...@amd.com>

If there are no CCP devices on the system, ccp-crypto will not load.
Write a message to the system log clarifying the reason for the failure
of the modprobe operation

Signed-off-by: Gary R Hook <gary.h...@amd.com>
